Limitations

This assessment has been prepared in respect of the proposals and should not be interpreted as a report on tree health and safety. Reasonable effort has been made to identify visible defects whilst undertaking the tree survey; trees are however, prone to natural failure without warning therefore no guarantee can be made as to the absolute safety of any of the trees surveyed. Aspect’s opinion of tree condition and structural potential is therefore valid for a limited period of 12 months from the date of inspection. Validity is assumed in the absence of inclement weather and no change to the trees’ existing context. Reliance should not be given to comments made in respect of other disciplines i.e. landscape, ecology or civil engineering without first consulting an appropriate expert.

Woodcock Hill Village Green, Borehamwood, Hertfordshire Arboricultural Impact Assessment

October 2020 1 | Page

Executive Summary

i) Introduction. Aspect Arboriculture are commissioned by Taylor Wimpey Strategic

Land to undertake an Arboricultural Survey and produce a subsequent Arboricultural

Impact Assessment in respect of the proposed introduction of footpaths within two

parcels of woodland at Woodcock Hill Village Green, Borehamwood.

ii) Proposals. The proposals seek consent for the deregistration of an area of village

green, and the provision of a replacement area of new village green.

iii) Surveys. The site was surveyed by Aspect Arboriculture during October 2020 following

the guidance contained within BS5837:2012.

iv) Statutory Designations. Background checks have revealed that the site does not occur

within a Conservation Area. Both woodland parcels are afforded protection by a TPO

designation.

v) Arboricultural Impact. The arboricultural impact of the proposed footpaths is

described by net tree losses, totalling two low quality semi mature Hawthorn, with

limited understorey at the woodland edges, and saplings below the threshold for

BS5837 consideration. A preliminary tree retention and removal drawing is provided

to demonstrate the deliverability of the proposed footpath routes. Conclusions drawn

against British Standard guidance conclude that the footpaths can be installed without

harming the amenity, function or integrity of the woodland parcels.



1 Introduction 1.1 Background & Proposals

1.1.1 The proposals seek consent for the deregistration of an area of village green, and the

provision of a replacement area of new village green. As part of the proposals, it is

necessary to provide pedestrian access from the retained area of Village Green to the

replacement area. The purpose of this document is to determine the arboricultural

effect of the proposals.

1.2 Existing Trees

1.2.1 The parcels of woodland are linear in shape and orientated approximately northwest

– southeast. Both parcels collectively form a continuous feature connected but offset

in their alignment. Current public access appears to be informal, consisting of trodden

paths within the parcels of woodland, located immediately to the west of, and

accessed from the existing Woodcock Hill Village Green, and also abutting Byron

Avenue as illustrated within Figure 1 below:

Figure 1: Aerial view of the parcels of woodland dated 2018

(Google Earth, cited October 2020)

1.2.2 The two parcels of woodland are markedly different in structure and character and are

described below:



Northern Parcel

1.2.3 The northern parcel of woodland is located on a large earth bund, aligned roughly

north-south, Located immediately adjacent to the route of the Elstree railway Tunnel

(constructed 1862), it is understood that the bund comprises the arisings from the

tunnel’s construction.

1.2.4 The northern parcel contains extensive understorey majoring on Hawthorn, with a

smaller proportion of Spindle, Blackthorn, and Crab Apple; extensive bramble growth

is present towards the northern extent. Much of the understorey is multi stemmed,

consistent with now lapsed management practices and/or herbivore damage/grazing

previously.

1.2.5 The dominant canopy trees are primarily located on the eastern and southern

boundaries majoring on mature Ash and English Oak. The siting of these trees

coincides with the pre-existing network of field boundary hedgerows shown at figure

2 below.

1.2.6 The woodland interior and especially the eastern extent is noticeably less established,

and is formed primarily of semi mature and early mature Ash, English Oak, Field Maple

& Sycamore. These trees are representative of ongoing natural colonisation of the area

through absence of management. Indeed, and illustrated within Figure 2, as recently

as 2000, the eastern and central extent of the parcel of woodland was sparce,

comprising isolated trees set within grassland.

(Google Earth October 2020)

Southern Parcel

1.2.7 As illustrated within Figure 2 above, the southern parcel of woodland is more

established than the north. Resulting from its more established canopy layer, the

southern parcel is also more open in structure at ground level, with a less dense

understorey.



1.2.8 The appearance of the woodland is formed by English Oak and Ash, with occasional

Poplar and Horse Chestnut. Similar to the northern parcel, mature trees are present

within the alignment of the pre-existing field boundary hedgerows, which form the

eastern and northern extents of the parcel. The western boundary of the parcel is

defined by a lapsed intermittent hedgerow, majoring on Hawthorn. Internally, the

trees vary between young regeneration and early mature components.

1.2.9 Of note, a number of the early mature Oak have been subject to fairly extensive basal

herbivore damage, and their condition should be monitored. Similarly, at the time of

the survey, an early mature Poplar was exhibiting major storm damage, with large

hung up scaffold branches, which should be removed in the interesting of abating the

hazard currently posed. Away from areas of frequent public access, defects and

deadwood is are acceptable within woodland as part of its intrinsic value.

1.2.10 Young regenerative Ash frequently demonstrate infections with Hymenoscyphus

fraxineus (Ash dieback). It is recommended that the progress of this is monitored, with

significantly declining components removed as necessary.



2 Designations 2.1 Conservation Area

2.1.1 Background checks have revealed that the application area does not occur within a

Conservation Area (HBC, October 2020). Accordingly the amenity value of the trees is

not elevated to preserving or enhancing any unique or distinctive interest linked to the

setting.

2.2 Tree Preservation Orders

2.2.1 Background checks have confirmed that both parcels of woodland are afforded

protection by separate Tree Preservation Orders: TPO No. 387/1997 schedules the

southern parcel of woodland, and the southernmost extent of the northern parcel as

W1 within the order; TPO No. 23/2010 affords protection to the northern parcel of

woodland, as part of a wider W1 area extending to the north, either side of the railway

line (HBC, October 2020).

2.3 Ancient and Veteran trees and Ancient Woodland

2.3.1 Searches also reveal the absence of records for ancient or veteran trees within

influence of the site1. This has been verified on the ground during the tree surveying

process. Accordingly there are no trees that might be judged to be irreplaceable or of

exceptional biodiversity, cultural or heritage value because of their age, size and

condition. There is no ancient woodland present2.

3 Arboricultural Impact 3.1 Net Tree Removals3

3.1.1 The routes for the proposed footpaths and woodland walk have been designed onsite,

accounting for the existing tree cover and topographical features. The routes are

illustrated with a dashed yellow line within Appendix C and have been plotted using

GPS coordinates.

3.1.2 The trees within influence of the proposed footpath routes have been surveyed

following the guidance of BS5837:2012, and have been located using GPS data. These

are illustrated within the Tree Constraints Plan at Appendix A and the Tree Retention

and Removal Plan at Appendix C, with full details of the tree cover contained within

the accompanying tree Survey Schedule at Appendix B.

3.1.3 By design the majority of the footpath through the northern parcel of woodland

follows the route of an existing informal footpath passing between established canopy

trees and understorey (refer to viewpoint location plan and photosheets included at

Appendices E & F). Aspect Arboriculture have designed the path to provide a

pedestrian link between the replacement Village Green and Byron Avenue in the

north, connecting directly with Hertsmere BC land. If this is not deliverable for

contractual reasons, will still be practicable to provide a circuitous walk to be provided

via the illustrated loop within the woodland’s northern extent.

3.1.4 The direct arboricultural impact of introducing either the link with Byron Avenue or

the circular woodland walk are identical. The only tree removal, other than saplings

and minor understorey components, are two semi mature Hawthorn (T117 and T210)

towards the route’s southern extent where it links with the replacement Village Green

land.

3.1.5 The proposed footpath routes through the southern parcel of woodland are required

to provide pedestrian connectivity between the retained area of Village Green to the

west, and the replacement area to the east. Due to its more open structure at ground

level, and less varied topography, the two routes through the parcel of woodland have

been designed to pass between the established canopy trees.

3.1.6 Subsequently both proposed routes through the southern parcel will necessitate only

the limited removal of edge understorey components and scrub to provide access into

the woodland interior from the adjacent areas of open space and internally, saplings

from within the footprint of the proposed footpath routes.

3.1.7 In addition to the BS5837 survey of trees within influence of the proposed footpath

routes, Aspect Arboriculture have also undertaken a systematic count of the trees

3All tree works should be timed to avoid the main nesting season for birds between 1st March and 31st August. If scheduled within this period it is recommended that an ecologist is present to advise on any necessary protective measures, and on hand to confirm that tree works are not likely to cause disturbance to nesting birds.



within each woodland parcel. In accordance with BS5837:2012 guidance, this included

all dominant canopy trees and established understorey over 150mm diameter. To

summarise, the northern parcel of woodland contains 300no. trees, and the southern

parcel 127no. trees. Of these, none will be required to be removed to implement any

of the proposed footpath routes. The outward appearance of the woodland in terms

of its cohesive structure will therefore remain unchanged.

3.1.8 To confirm, the minimal tree removals necessary to introduce all proposed footpath

routes will not incur the removal of any dominant canopy trees, and will not affect the

amenity contribution currently provided by either parcel of woodland.

3.2 Vulnerable Trees

3.2.1 The proposed footpaths and woodland walk will comprise a non-invasive woodchip

wearing course (maximum 200mm depth), overlain on a permeable membrane, and

retained to each side with pegged timber edges. Whilst the entirety of all routes,

through both parcels of woodland will unavoidably cross Root Protection Areas, the

impact of the footpath will be negligible. The guidance within clause 7.4.2.3 of BS5837

is not appropriate in this instance, because it is not proposed to introduce any hard

surfacing within the Root Protection Areas.

3.2.2 It is not anticipated that any excavation will be necessary, nor will the installation of

the paths require compaction of the soil to forma subbase. Similarly, the construction

of the footpaths provides the capacity to cross surface root without risk of harm. The

construction of the paths will retain its permeability to water and ensure that the

subterranean rooting environment retains its gaseous exchange properties.

3.2.3 Maintenance is of the footpaths will also be low impact, and will comprise the

periodical removal of weeds, and the application of additional woodchip in areas that

become waterlogged.

3.3 Pruning Works

3.3.1 The only pruning works anticipated relate to the limited crown lifting of the trees

oversailing the proposed footpath routes, to provide c.2.4m clearance. In all cases the

extent of pruning will be determined onsite, but is anticipated to amount to the

removal and shortening of minor lower branches only. The proposed works will be

readily achievable without harm to the physiological and structural potential of any

affected trees. These works will not harm the external appearance of the woodland.

3.3.2 Although not required to facilitate construction, it is Aspect Arboriculture’s

recommendation that over and adjacent to the proposed footpath routes, dead

branches are removed from the canopies of retained trees. This will help mitigate the

risk of future tree related hazards emerging, whilst facilitating public access and

appreciation of the parcels of woodland. Other tree works related to the provision of

safe access are included within the Woodland Management Plan – (ref:

10790_WMP.001).



3.3.3 Pruning works should be undertaken in accordance with section 7.3 (for removal of

deadwood), section 7.7 (for crown lifting), and section 7.8 (for selective pruning) of

BS3998:2010, by a competent tree contractor. This is necessary to ensure that cuts are

performed correctly and positioned so as to avoid future structural defects or

physiological issues, facilitate growth and maintain aesthetic value.

3.4 Mitigation Replanting

3.4.1 The tree removal necessary to introduce the proposed footpaths is minimal, and will

not affect the amenity contribution currently provided by the parcels of woodland. As

such, there is no requisite need for mitigation replanting.

3.4.2 It is however recommended that restocking is introduced as part of a programme of

woodland management, the intention of which is to improve the structure and

condition of both parcels of woodland. It is also recommended that where Ash are

removed during the course of management, resulting from the presence of Ash

dieback, that they are replaced with English Oak and Sweet Chestnut standards. This

will ensure the presence of a long lived, large canopy species, thereby providing

succession planting for the more mature English Oak components, located on the

historical field boundary alignments.

4 Conclusions

4.1.1 It is technically feasible to introduce three proposed pedestrian footpath linkages

through two parcels of protected woodland adjacent to Woodcock Hill Village Green,

Borehamwood. The proposed routes have been designed onsite to avoid conflict with

the existing established tree cover and associated topographical features which might

otherwise result in cumulative harm to the woodland.

4.1.2 The installation and use of the proposed footpath routes will necessitate the removal

of two semi mature Hawthorn and the limited clearance of understorey edge

components and saplings. The construction and use of the proposed footpaths and

woodland walk will not require the removal of any dominant or canopy layer trees.

Subsequently, tree removals are low in number, low in arboricultural value and

extremely limited in terms of potential for harm to amenity.

4.1.3 Since public access is prerequisite in attaining the public benefits attributable to trees,

there is inherent gain from providing development enabled access to the woodland.

4.1.4 Based on the above and subject to implementation of the mitigation measures

outlined in this report, the arboricultural effect of the footpath proposals is fully

supportable in terms of British Standard guidance. The proposals will also facilitate the

positive management of the woodlands, thereby conserving and enhancing the

structure and condition of these amenity assets.

APPENDIX D

TREE SURVEY METHODOLOGY

Woodcock Hill Village Green, Borehamwood, Hertfordshire Tree Survey Methodology

Tree Survey Methodology

The tree survey is a form of Visual Tree Assessment undertaken during October 2020. Tree locations are

identified via a topographical survey; locations of any trees excluded from the topographical survey

were plotted on site. The purpose of the survey is to record information about trees on or adjacent to

the site to inform design options. In keeping with clause 4.4 of BS5837: 2012 ‘Trees in Relation to

Design, Construction and Demolition’, the survey provides a record of the following parameters:

Tree Numbers: all individual trees are sequentially numbered. Groups of trees, woodlands and

hedgerow are also sequentially numbered with a corresponding prefix relevant to their type e.g. G, W or

H respectively; the identification of trees as woodland, groups of trees or within hedgerows is

undertaken where appropriate. The identification of trees as individuals within collections has been

made where it is considered sensible to make such a differentiation.

Species: listed by common name

Stem Diameter: given in millimetres and obtained by measuring single/multiple stems at 1.5m using a

diameter tape in accordance with Annex C within BS5837:2012. Diameters of inaccessible trunks are

estimated and provided with the suffix ‘#’.

Tree Heights: determined using a clinometer and measured to the nearest 500mm. Heights are

estimated where specific triangulation is not achievable and by reference to measured trees nearby

(provided with the suffix ‘#’).

Crown Spreads: measured at cardinal points using a Leica DistoTM laser distance measurer.

Measurements were recorded to the nearest 250mm. Inaccessible crown spreads are estimated based

on measured canopies nearby and provided with the suffix ‘#’

Crown Clearance: The height of the first significant living branch and/or canopy (as appropriate) is

recorded using a Leica DistoTM laser distance measurer to inform vertical ground clearance. Crown

clearance may be higher or lower than the first significant branch. Estimated clearances are provided

with the suffix ‘#’. Height of first significant branch will be provided where considered advantageous to

make the distinction.


Life Stage – The age of trees, groups of trees, hedges and woodlands are defined as follows:

• Young (within the first 1/4th of life expectancy)

• Semi-mature (within the second 1/4th of life expectancy)

• Early Mature (within the third 1/4th of life expectancy)

• Mature (within the fourth 1/4th of life expectancy)

• Over Mature and Veteran (exceeding normal life expectancy)

• Veteran (significantly exceeding normal life expectancy)

Physiological and structural condition: physiological condition defined as follows; good, above average,

average, below average, poor or dead. Structural condition is defined as: good, moderate, indifferent,

poor or hazardous

Comments: further observations were recorded where necessary i.e. details regarding defects,

preliminary management recommendations, presence of pest/disease and perceived significance.

BS5837 Category: pursuant to BS5837:2012 section 4.5 and cascade chart for tree quality assessment

(refer to reproduced Table 1 overleaf). Trees qualifying under a given category (A-C and U) and any

appropriate subheading (1-3) are considered to fall within the scope of that category’s definition.

Estimated Remaining Contribution. Described` as a guideline only and in terms of years: <10, 10+, 20+

and 40+ relevant to category U, C, B and A respectively. This information is not provided on the tree

schedule to avoid conclusions based upon ‘life expectancy’.
